Today’s recipe is ideal for vegetarians and can be served for any occasion, from lunchtime through dinner, for an appetizer or tapas. I try to keep a repertoire of meatless recipes on hand, besides the fact this casserole is so sabroso yet easy to prepare. You’ll be impressed by just how rico this leek, mushroom and cheese casserole is–the fla-vors work together so well. I usually serve my casserole accompanied by a fresh green salad and a glass of crisp white wine.

    Separately, melt the butter in a large non-stick skillet over medium heat. Add-in the leeks, thyme and sprinkle a bit of salt and pepper on top. Cook until the leeks are ten-der, but not browned. Make sure to stir frequently for about 10 minutes. Last, combine with the diced mushrooms and continue to sauté for about 3 more minutes. When ready, remove from heat and set aside.
